AI included — no subscriptions
Sound Copilot ships with its own AI engine powered by Llama under the hood. There is no OpenAI, Anthropic, or other cloud API to configure—everything runs on your machine as part of the plugin.
Default agent
Out of the box, Sound Copilot uses a tuned default agent optimized for music production workflows. It is ready to use as soon as you install the plugin—no API keys, no billing, no extra setup.
Different agents can produce different styles of answers. If the default does not match your taste or you want a specialist for a particular role, you can switch to another compatible agent (see below).
Response times
Because the AI runs entirely on your machine, response times vary widely. There is no fixed cloud latency—speed depends on your hardware and the agent you choose.
- How much RAM you have available
- Your processor (chip generation and core count)
- Your graphics card (GPU model and available VRAM)
- Which agent you use—larger GGUF models are generally slower
- Platform: on macOS, Sound Copilot can use Metal GPU acceleration. On Windows, inference uses a mix of GPU and CPU—ideally all GPU when your hardware allows.
As rough references with the bundled agent: about 30 seconds on a Mac M1 Pro, and about 20 seconds on Windows with an NVIDIA GeForce GTX 1080 and 32 GB of RAM. Your results may be faster or slower depending on your setup.
Install a custom agent (GGUF)
You can download a Llama-compatible .gguf model and use it as your Sound Copilot agent. Rename or save the file as sound_copilot_agent.gguf and place it in the models folder for your platform.
macOS
~/Library/Application Support/SoundCopilot/models/sound_copilot_agent.ggufWindows
%APPDATA%\SoundCopilot\models\sound_copilot_agent.gguf- Download a compatible Llama GGUF model from a trusted source.
- Create the models folder inside the Sound Copilot application support directory if it does not exist.
- Copy the file as sound_copilot_agent.gguf.
- Restart REAPER or reload Sound Copilot to pick up the new agent.
Privacy
Your raw audio never leaves REAPER. Sound Copilot analyzes audio locally (pre/post FX for audio tracks, instrument data for MIDI), then the built-in Llama engine processes that summary together with your project context—all on your machine.
